DEFECT #3 - SUSPENSION:REAR:SPRINGS:LEAF SPRING ASSEMBLY
Posted on: 1979-10-12
Description
Some of the vehicles may have manganese bronze spring clip plates used as a substitute for malleable iron. The substitute clips, which are used to attach the suspension spring to the rear axle, may crack allowing the assembly to loosen. This can cause rear axle displacement.
Consequence

DEFECT #4 - SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE
Posted on: 1979-10-12
Description
The involved vehicles may have been built with power unit anti-skid logic modules on tag axle installations instead of the correct trailer type modules. Since the tag axle sensor output is less than that of the power unit sensor, it requires the more sensitive trailer module. As sensor output over time drops below minimum requirements, one of two things will happen: (1) the anti-lock system on the tag axle will shut down and the cab mounted fault lamp will light or (2) the system will become inoperative without activating the fault light. This fails to conform to federal motor vehicle safety standard no. 121, air brakes.
Consequence
Corrective Action
Dealer will replace the incorrect anti-lock module without charge to owner.
Notes
Vehicle description: truck tractors.system: service brakes; vacuum brake system.consequences of defect: if the system becomes inoperative, a brake lock-up,loss of vehicle control and an accident could occur without prior warning.note: the electrical power to the anti-lock system should be disconnected byremoving the anti-lock system fuse until the defect can be corrected.
DEFECT #5 - SERVICE BRAKES, AIR:SUPPLY
Posted on: 1979-10-12
Description
The involved vehicles were built with certain tractor protection valves which may contain an extra valve. This may prevent the trailer brakes from fully releasing after a low pressure application, causing the trailer brakes to drag.
Consequence
Corrective Action
The dealer will inspect for the presence of the extra check valve. If found, the extra check valve will be removed. This will be done at no charge.
Notes
Vehicle description: truck tractor.system: service brakes; protection valves.consequences of defect: overall braking efficiency and vehicle control may beimpaired. This could lead to a vehicle accident.note: the only precaution drivers may take to reduce the risk of malfunctionprior to corrective action is to operate the vehicle bobtail.
